Hadron Spectroscopy

الأصل · EN

Recent results on the hadron spectroscopy from lattice QCD are reviewed with emphasis on the meson sector and in particular on quarkonium-like XYZ states. I report on the first rigorous treatment of the near-threshold states X(3872) and Dₛ⁰(2317), and the lattice searches for Zc+(3900), X(4140) and double-charm tetraquark states. Meson resonances in light, strange and charm sector are reviewed, where the resonances masses as well as the strong decay widths are reported. The first lattice QCD simulation of two coupled-channels is discussed.
